I know it's impossible to move faster than light, this is merely hypothetical.
When you move faster than light, you have infinite mass. Now, surely if that thing with infinite mass crashed into anything, wouldn't an infinite force would be produced (F=MA) ?
And wouldn't that force kinda fuck shit up?

Who said you have infinite mass? Don't you mean infinite energy? If you had infinite mass, you wouldn't be going anywhere since it would probably take more energy than what's in the universe to move you.
